Answer to Question #232764 in Physics for Jennie mae

Question

Solve the unknown value

Force Mass Acceleration 1. 45 kg 7.6 m/s²

2. 255 N 11.25 m/s²

3. 546 N 35 kg

4. 45 N 11 m/s²

5. 85 kg 8 m/s²

Answer 1

1

$$F=ma=1.45\:\rm kg*7.6\: m/s^2=11\: N$$

2

$$m=\frac{F}{a}=\frac{255\:\rm N}{11.25\:\rm m/s^2}=22.7\:\rm kg$$

3

$$a=\frac{F}{m}=\frac{546\:\rm N}{35\:\rm kg}=16\:\rm m/s^2$$

4

$$m=\frac{F}{a}=\frac{45\:\rm N}{115\:\rm m/s^2}=4.1\:\rm kg$$

5

$$F=ma=85\:\rm kg*8\: m/s^2=700\: N$$
